Kae Serinuma is a high school sophomore and a passionate "fujoshi," an obsessive fan of boys' love (yaoi) anime and manga. Deeply immersed in her imaginary shipping fantasies, Kae is largely
indifferent to real-life romance until her favorite anime character, Shion, is killed off. Devastated by this tragedy, she locks herself in her room for a week without eating. When she finally emerges, the sudden extreme weight loss has completely transformed her appearance from a chubby, bespectacled girl into a stunning, conventionally attractive beauty.Her dramatic physical change instantly captivates four very different boys at school: Nozomu Nanashima, a flashy tsundere; Yusuke Igarashi, a dependable jock; Asuma Mutsumi, a gentle and scholarly senior; and Shinomiya Hayato, a prideful, effeminate underclassman. Despite vying for her affections, the boys are completely bewildered and often horrified when Kae tries to push them into romantic entanglements with each other rather than pursuing her herself. Kae’s primary motivation remains pure fujoshi bliss; she views their clumsy romantic overtures through the lens of a fictional BL plot, much to the exasperation of her suitors.As the story progresses, the romantic competition intensifies. The boys attempt various dates and bonding activities to win her heart, only for Kae’s otaku tendencies to derail their plans, whether by dragging them to obsessive convention events or interpreting their genuine jealousy as romantic tension directed at each other. The dynamic shifts further with the introduction of Shima Nishina, a talented, wealthy first-year manga artist who is not only a fellow hardcore fujoshi but also a master of disguise. Shima becomes Kae’s ultimate rival and dearest confidante, frequently teaming up with Kae to orchestrate elaborate scenarios just to watch the boys interact.Despite viewing them initially as mere "shipping material," Kae slowly begins to see the boys as genuine individuals who care deeply for her well-being. Mutsumi, in particular, proves to be a steady presence who loves Kae for who she is on the inside, regardless of her weight or her eccentric hobbies. Ultimately, after navigating countless comedic misunderstandings, otaku conventions, and emotional hurdles, Kae must confront her own feelings. She is forced to choose between remaining in her comfortable
fantasy world of fictional romance or taking a brave leap into the unpredictable, messy reality of true love.
